Dan Lorenc is the Co-founder and CEO of Chainguard, the safe source for open source.

The internet runs on free, open source software. But as its risen in popularity, its become the latest attack point targeted by hackers and nation states.

This conversation with Dan gets into the history of open source software, cloud computing, Linux, the software supply chain, how AI will impact it, and what the next big cyber attack will look like.

Dan is an engineer, but he also loves sales and go-to-market. We unpack how Chainguard went from zero to 150 customers and a $40m ARR in two years.

Chainguard just announced a $350 million Series D led by Kleiner and IVP, and Dan unpacks the round, plus shares his secret methodology for valuing the company.

A big thank you to Dan’s Co-founder Kim Lewandowski, to Clay Fisher @ Spark, Bogomil Balkansky & Andrew Reed @ Sequoia, and Tom Loverro @ IVP for their help brainstorming topics for Dan.
